sempite-python

Python client for the SEMPITE AI Search Visibility API — check whether AI engines (ChatGPT, Google AI, Perplexity, Gemini, Claude) know your brand, and whether they cite your website.

Zero dependencies (standard library only). Python 3.8+.

Install

pip install sempite

Or just copy src/sempite/__init__.py into your project — it's one file.

Quickstart

from sempite import SempiteClient

client = SempiteClient("sk_live_...")   # or set the SEMPITE_API_KEY env var

result = client.check("Acme Coffee Roasters", domain="acmecoffee.com")

print(result["visibility_score"])              # 0-100, share of engines that know the brand
for engine, r in result["engines"].items():
    print(f"{engine}: present={r.get('present')} cites_site={r.get('cites_site')}")
    # r["snippet"] holds the first 400 chars of the engine's actual answer

Custom prompt, market, engine subset

result = client.check(
    "Acme Coffee Roasters",
    domain="acmecoffee.com",
    market="uk",                          # us (default), es, mx, uk
    prompt="Best specialty coffee roasters in London?",
    engines=["chatgpt", "perplexity"],    # default: every engine your plan includes
)

Usage / quota

print(client.usage())
# {'plan': 'starter', 'month': '2026-07', 'checks_used': 12,
#  'checks_quota': 250, 'checks_remaining': 238}

Engines & plans

Free = 10 checks/month · Starter ($29/mo) = 250 · Pro ($99/mo) = 1,000. Rate limit: 10 requests/minute per key.

Errors

from sempite import SempiteClient, AuthError, QuotaError, RateLimitError, SempiteError

try:
    result = client.check("Acme")
except QuotaError as e:        # 402 — quota reached or engine needs a paid plan
    print(e, "→", e.upgrade_url)
except RateLimitError:         # 429 — slow down (10 req/min)
    ...
except AuthError:              # 401 — bad or revoked key

  "checks_quota": 10,
  "plan": "free",

}

visibility_score = share of successfully-queried engines that recognized the brand (name present, no refusal). cites_site = the engine's answer mentioned your domain.
